A number of forum members have posted about taking Dacogen. There's a thread named
Starting Dacogen and a more recent one named
Dacogen for MDS. You'll find others if you use the
forum search page and search for dacogen or decitabine.
Did they rule out a transplant due to your father's age?
To get the bigger picture I suggest that you contact the Aplastic Anemia & MDS International Foundation and get their free booklets named "Your Guide to Understanding MDS" and "A Guide to Understanding FDA Approved Drug Therapies for MDS". See their
order form.
I also recommend reviewing the
patient information from the MDS Foundation, especially
Understanding Myelodysplastic Syndromes: A Patient Handbook (PDF, 220K).
